Standard Quantity or Hours Standard Price or Rate Standard Cost Direct materials Direct labor $3.00 per yard per direct labor- $ 2 hour Variable manufacturing overhead Total standard cost per unit Overhead is applied to production on the basis of direct labor-hours. During March, 570 backpacks were manufactured and sold Selected information relating to the month's production is given below: Variable Materials Used $ 8,550 $ 6,080 Direct Manufacturing Labor Overhead $1,596 $2,812 Total standard cost allowed* Actual costs incurred Materials price variance Materials quantity variance Labor rate variance Labor efficiency variance Variable overhead rate variance Variable overhead efficiency variance $6,384 $ 570 U For the month's production. The following additional information is available for March's production Actual direct labor-hours Difference between standard and actual cost per backpack 855 $ 0.20 F produced during March Required Hint: It may be helpful to complete a general model diagram for direct materials, direct labor, and variable manufacturing overhead before attempting to answer any of the requirements. 1. What is the standard cost of a single backpack? 2. What was the actual cost per backpack produced during March? 3. How many yards of material are required at standard per backpack? 4. What was the materials price variance for March if there were no beginning or ending inventories of materials? 5. What is the standard direct labor rate per hour? 6. What was the labor rate variance for March? The labor efficiency variance? 7. What was the variable overhead rate variance for March? The variable overhead efficiency variance? 8. Prepare a standard cost card for one backpack
